For the CMR cine la4Ch segmentation model, the Dice metrics between automated and manual segmentations were 0.97 for the LV blood pool, 0.92 for the LV myocardium and 0.96 for the RV blood pool, which is in line with previous published methods [1]}, [2]}. For the echocardiography apical 4Ch segmentation network, similar to [3]}, the Dice metric between automated and manual segmentations was 0.96 for the LV blood pool.
